Soft Spot Software that turns your wi-fi connection into a "phone line"? You bet, and it could save you big bucks.

As more phone traffic travels over the Internet, more computers will be doubling as telephones. Any Internet-connected desktop, laptop, tablet or PDA with a mic and speakers can become a softphone by adding a small inbox/dialer client that links to an Internet-connected server elsewhere.

Why bother? Because calls traveling exclusively over the Internet cost the same whether the other party is across the street, across the country or around the world- and that cost is usually zip, zero, nada.

Another reason is that, technically, the Public Switched Telephone Network (PSTN) and even cellular networks don't actually route calls to you personally; they call a handset. IP phone systems do a much better job of tracking you down wherever you may roam-and these days, more of us spend more time out of the office than ever before.
